Thursday brings the first trailer for Jonathan Liebesman‘s reboot of Teenage Mutant Ninja Turtles. Monday, however, the trailer debuted at CinemaCon in Las Vegas, NV, where it generated a little wave of controversy. Apparently, the trailer suggests April O’Neil’s father, along with Shredder, helped create the ooze that created the turtles. Read more about the Ninja Turtles movie origin below.

The description and suggestion comes from Badass Digest. Here’s an excerpt of the piece.

At first the trailer hides the turtles – there’s voice over from William Fichtner’s Shredder explaining the city has gone to shit. We see criminals with automatic weapons and buildings exploding and maybe – just maybe! – it seems like this could be a Hobo With A Shotgun version of a city in decline. It turns out that this version of Shredder hates that crime and violence, and so he started a program to create heroes. That’s juxtaposed with TCRI ooze canisters and experiments. You know, the ooze that created the turtles. The ooze that Shredder made… with April’s dad. Yes, the VO is Shredder telling April he and her dad made the turtles.

The common origin of the turtles is that they just kind of happened on this mysterious ooze in the sewers. Some of the comics, TV shows and movies have different versions of this, some of them even relate to Shredder’s Foot clan, but none of them tie in April O’Neil (played here by Megan Fox) or her father at all.

If this is true, and we’ll likely know more on Thursday when we all see the trailer, the question is does this change in the origin make fans mad? Fans went crazy when rumors circled the turtles were going to be aliens, but that doesn’t happen in the finished film. This is much slighter change – they’re still created by ooze in a sewer thankfully – but it’s a big enough one some fans are sure to be upset.

Check back on Thursday for the full Teenage Mutant Ninja Turtles trailer but, until then, what do you think of this change?
